My idea was to create a repository with already made SQL schemas that I've used different places. It was mostly to avoid doing the same thing over and over again and for others to not have to create everything from scratch either.
Currently the package contains Oracle, MySQL, and Postgresql version of countries and states tables including the data that goes in there.
If you have something you'd like to contribute to the SQL Schema Repository you can email me with suggestions (Email found in the downloadable package).
The SQL Schemas are released under the GPL license.
The package can be downloaded from here.
If you want to view the contents before downloading the files you can access the cvs repository from here.
